I have a new 1301 tactical Gen 2 shotgun, What size wrench is needed to loosen the front sight? Can slugs be used with the factory installed choke? any particular slugs? What choke is in there?

1301 Gen. 2 Shotgun

The wrench size for the front sight is 5.5 mm. The factory installed choke tube is Cylinder. which is the correct choke to use when shooting slugs.
